Sub-Wavelength Terahertz Spin-Flip Laser Based on a Magnetic Point-Contact Array

We present a novel design for a single-mode, truly sub-wavelength THz disk laser based on a nano-composite gain medium comprising an array of metal/ferromagnetic point contacts embedded in a thin dielectric layer. Stimulated emission of light occurs in the point contacts as a result of spin-flip relaxation of spin-polarized electrons that are injected from the ferromagnetic side of the contacts. Ultra-high electrical current densities in the contacts and a dielectric material with a large refractive index, neither condition being achievable in conventional semiconductor media, allows the thresholds of lasing to be overcome for the lowest-order modes of the disk, hence making single-mode operation possible.Comment: 9 pages,4 figure

A Mega-Analysis of the Effects of Feedback on the Quality of Simulated Child Sexual Abuse Interviews with Avatars

The present study aimed to test the effectiveness of giving feedback on simulated avatar interview training (Avatar Training) across different experiments and participant groups and to explore the effect of professional training and parenting experience by conducting a mega-analysis of previous studies. A total of 2,208 interviews containing 39,950 recommended and 36,622 non-recommended questions from 394 participants including European and Japanese students, psychologists, and police officers from nine studies were included in the mega-analysis. Experimental conditions were dummy-coded, and all dependent variables were coded in the same way as in the previously published studies. Professional experience and parenting experience were coded as dichotomous variables and used in moderation analyses. Linear mixed effects analyses demonstrated robust effects of feedback on increasing recommended questions and decreasing non-recommended questions, improving quality of details elicited from the avatar, and reaching a correct conclusion regarding the suspected abuse. Round-wise comparisons in the interviews involving feedback showed a continued increase of recommended questions and a continued decrease of non-recommended questions. Those with (vs. without) professional and parenting experience improved faster in the feedback group. These findings provide strong support for the efficacy of Avatar Training

Confirmation bias in simulated CSA interviews: How abuse assumption influences interviewing and decision‐making processes?

Purpose Research has shown that confirmation bias plays a role in legal and forensic decision-making processes and, more specifically, child interviews. However, previous studies often examine confirmation bias in child interviews using non-abuse-related events. We enrich the literature by examining interviewers’ behaviours in simulated child sexual abuse (CSA) cases. Method In the present study, we used data from a series of experiments in which participants interviewed child avatars to examine how an assumption of abuse based on preliminary information influenced decision-making and interviewing style. Interview training data (N interview = 2084) from eight studies with students, psychologists and police officers (N = 377) were included in the analyses. Results We found that interviewers’ preliminary assumption of sexual abuse having taken place predicted 1) a conclusion of abuse by the interviewers after the interview; 2) higher confidence in their judgement; 3) more frequent use of not recommended question types and 4) a decreased likelihood of reaching a correct conclusion given the same number of available relevant details. Conclusion The importance of considering how preliminary assumptions of abuse affect interview behaviour and outcomes and the implications for the training of investigative interviewers were discussed

Parental satisfaction and seizure outcome after corpus callosotomy in patients with infantile or early childhood onset epilepsy

AbstractPurposeTo elucidate the benefit of corpus callosotmy in terms of parental satisfaction and seizure outcome.MethodThis study included 16 consecutive patients with infantile or early childhood onset epilepsy who underwent total corpus callosotomy for alleviation of seizures. Questionnaires were sent anonymously to the parents asking about relative changes in seizures and about parental satisfaction for the post-operative outcome.ResultsThe improvements in frequency, intensity, and duration of seizures were correlated with the level of satisfaction (Spearman's rank-order correlation coefficient, ρ=0.87, 0.93, and 0.75, respectively). The highest level of satisfaction was only seen in patients who achieved freedom from all seizures or drop attacks.ConclusionComplete seizure freedom and freedom from drop attacks are important goals of corpus callosotomy for parental satisfaction. These factors should be considered in assessing post-operative outcome after corpus callosotomy
